Got a Windows 10 PC that has a black screen with a mouse cursor after login/boot? I'll show you how to fix this issue! This also works with Windows 8.1, Windows 8 and Windows 7, and it works under virtualisation software like VirtualBox.
How to FIX Windows 7/8/10 Black Screen of Death With Cursor After Login/Boot
So essentially what happens is that you log in and you're greeted with a black screen and a mouse cursor - nothing else. Now there's two ways to fix this problem in Windows 10/Windows 8/Windows 7; I'll show you the temporary fix first, and then the permanent one. The easy temporary fix is to press
Control Alt Delete , and click on
Task Manager from the menu that comes up. Click
File ,
Run New Tas k, and type "
explorer.exe ". This should bring your Windows 10 desktop back, but the only disadvantage is that you have to do this every time you start up your computer - not good.
Here's the more permanent fix, but be warned that it is more difficult! First, press
Control Alt Delete , click on T
ask Manager from the menu, click
File ,
Run New Task , and type "
regedit.exe ". Allow it to make changes to the computer by clicking
Yes .
Now, in the left-hand pane, click the little triangle next to
HKEY_LOCAL_MACHINE , scroll down and click the one next to
Software , click the one next to
Microsoft , click the one next to
Windows NT , and click on the
Winlogon folder -
not the triangle , the actual folder. Next, move over to the
right-hand panel , scroll down, and find the key called "
Shell ". Make sure that, under the "
Data " column, it says explorer.exe. See over here? Make sure that says explorer.exe. If it doesn't, then right click on the Shell key and click "
Modify ". Now change the value in this textbox to
explorer.exe .
Hopefully this helps you fix the issue.
